I'm going to suggest you do some reading first to bring yourself to the point where you understand what ISO 9001 is. There are a lot of areas fo go on this site alone. If you look around there is even a matrix or two which quite well define the basic relationships. Many, however, are alignments of QS-9000 and ISO 9001:1994.
The bottom line is they are both basic (minimum) 'requirements' for a quality system.
